Coffee Break vol. 2

Today's coffee break is happening in this Shawn Ireland cup. It's from way back when we were resident artists at Penland, probably 1999. For the longest time I drank out of it every morning, no lie. It's about 3 1/2 inches high and has some rare SPI brushwork, probably iron slip under a thin shino type glaze. There are a few small chips around the rim and it has a nice coffee stained interior from the thousands of cups of coffee I've enjoyed from it. How much is a beautiful pot worth? Especially one that one has derived so much enjoyment?
